在建筑中,外围护结构的热损耗较大,外围护结构中墙体又占了很大份额。所以建筑墙体改革与墙体节能技术的发展是建筑节能技术的一个最重要的环节,发展外墙保温技术及节能材料则是建筑节能的主要实现方式。外墙内保温施工,是在外墙结构的内部加做保温层。 In the building, the heat loss of the external envelope is larger, and the wall of the external envelope occupies a large proportion. Therefore, the reform of building wall and the development of wall energy-saving technology is one of the most important aspects of building energy-saving technology. The development of external wall thermal insulation technology and energy-saving materials are the main ways to achieve energy saving in buildings. External wall insulation construction, is to add external insulation in the outer wall structure.
